MILWAUKEE -

A Florida teenager who plummeted 100 feet from a Wisconsin amusement park ride in 2010 is getting some help from actor Charlie Sheen.

Teagan Marti, of Parkland, suffered brain, spine, pelvis and internal injuries when nets and air bags that were supposed to catch riders on the free-fall ride were not raised. She was paralyzed initially but through physical therapy is now able to walk with a walker.
